Power check
Connect a test light between the glow plug, cylinder 4 and ground.
Attention: If the engine does not start well, check the functions of automatic additional glow and glow during the start process.
1. After the pre-glow period has elapsed depending on the temperature (control lamp goes out), voltage should be present at the glow plugs for the next 6-7 seconds. During this check, do not turn on the starter. If there is no voltage at the glow plugs, the relay must be replaced.
2. During the startup process (starter included) voltage should be present at the glow plugs. If there is no voltage at the glow plugs, check the wire from the turnip to the glow plugs, between terminal 50 and the relay board, or replace the glow plug relay.
3. Connect according to the current wiring diagram.
